Summary of Flexible Package Integrity Testing

ASTM F1140 regulatory pouch and flexible package burst testing covers the ability of a flexible package to withstand internal pressurization. This test procedure is also known as package integrity testing or leak testing.

This test standard is frequently used to quickly evaluate packages during the manufacturing process and at various stages of the package’s life cycle. Additionally, ASTM F1140 provides a rapid means of evaluating tendencies for package failure when the package is exposed to a pressure differential. Pressure differentials may occur during processes such as sterilization and transportation.

Package evaluation can occur during the package’s life cycle. This helps find failures in the lab instead of in the field. ASTM F1140 package testing must consider many factors. These include but are not limited to package size, material and sensitivity. 

Other factors include seal configuration, sensitivity and rate of air flow into the package. There are two types of testing. First, there is burst testing. Second, there is creep testing.

ASTM F1140 Burst and Creep Testing Procedures

Burst Testing

Burst testing involves pressurizing a package until it fails. The internal pressurization is increased during testing. The test measure is the maximum pressure detected before the package fails.

The package can be tested with or without the packaged product. The package may be tested either open or closed. The failure is a visible observation and type of failure must be noted. An example of a pouch leak failure includes a seal failure or packaging material failure.

Creep Testing

Creep testing maintains a set pressure for a specific time. The testing can also result in a failure. The test measure is pass or fail.

The starting pressure is a percentage of the burst pressure. The typical starting point is 80%. This value may be raised or lowered as needed.

Package creep testing can be with or without the product enclosed. During inflation, the seal is observed. Deformations or seal breaks are noted. The test is complete once a set time is reached or the package fails.

Significance of ASTM F1140 Burst and Creepy Integrity Testing

ASTM F1140 package integrity testing provides insight on package failures from a pressure differential.

These differentials often occur during sterilization and transportation. The ASTM F1140 pouch and flexible package test standard is often required for medical packages. Many food packages undergo ASTM burst and creep testing as well.

After the test is complete, details of the package including the type of material and other characteristics will be added to the report. This can include date, time, location and test engineer. Additionally, the number of packages tested, the number of failures, and any conditioning are recorded as well.

For the burst test, the burst pressure value and location of the failure are included. For creep testing, the internal pressure and hold time are noted. For creep to failure testing, the internal pressure and hold time are included.

Expert Pressurization Failure Resistance Package Testing

Keystone has a full lab of test equipment which permits us to provide short lead times on scheduling. Our team strives to give our customers more time and energy on product development instead of testing.

We can accommodate flexible and rigid packages of all sizes, including large pallets. In addition to ASTM F1140 testing, Keystone has a full scope of expertise including leak penetration, cold chain, and drop.
